ADELBERT G. GUMAER AND JOHN G. W. KNOLL, OF BUFFALO,NE\V YORK.

SERPENTINE LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 374,960, dated December20, 1887.-

v Application filed August 2G, 1887. Serial No. 247,967. (No model.)

To all whom it may concern.-

Beit known'that we, ADELBERT G. GUMAER and'JoHN G. W. Kuoni., of thecity of Buffalo, county of Erie, and State of New York, have inventedcertain new and useful Improvements in Serpentine Lawn-Sprinklers, ofwhich the following is a specification, reference being had to theaccompanying drawings, in which- Figure l is a View of our sprinklerattached to the end of a hose pointing upward and.4

with the ends of the sprinkler-nozzles open. Fig. 2 is a view of thesprinkler attached to the end of ahose pointing downward and with theends of the nozzles closed. Fig. 3 is a section of a hose and couplingfor attaching our sprinkler, showing the perforated plug and the mannerin which we may connect the flexible tubes to it; and Figs. 4 and 5 aresectional views of the nozzles of the sprinklers detached.

The object of our invention is to produce ay lawnsprinkler that shallthoroughly distribute water in various small streams or jets and drop itall over a certain circular area as nearly like rain as practicable, andat the same time present a unique and attractive appearance and beconvenient to apply in use. To this end we provide aserpentine sprinklerto be connected to an ordinary hose or other device containing waterunder pressure, in the manner illustrated in the drawings, andhereinafter described.

Our invention consists in the combination of parts for particularimprovement of such a sprinkler, succinctly stated in our claims.

We mean by the phrase serpentine sprinkler7 a sprinkler that in actionmoves very much like a serpent fastened by its tail and wriggling andspringing about in a frantic endeavor to get away, and such is theappearance and action of our sprinkler. As it 'is composed of severalsmall wriggling serpentine tubes or sprinklers in a bunch, it presents alife-like appearance that arrests attention and interests spectators andforms a considerable feature of the practical utility of the device inoperation, because in practice the device is placed in show-windows andother conspicuous places for display and advertising purposes.

cap adapted to screw on over the couplingB I and to bear upon the top ofthe plug C and force it tightly into the coupling B.

F designates small hardrubber or other suitable tubes,which are firmlysecured within the holes D of the plug C. rlhese tubes are chaniiered atf to prevent their cutting the small flexible or serpentine rubber tubesG, which are secured to them. The tubes F are also provided with anannular roughened projection, f 2, to make a firm connection with thetlexible tubes G, as shown in thevdrawings. The tubes F might be omittedand the tubes G be made a part of or connected to the plug C. The tubesG are provided with nozzles H, made of hard rubber or other suitablematerial, and provided with one or more small openings, as illustrated,either in the end or at one side, or both.

I indicates a small screwsplug adapted to close the end hole in thenozzle H and cause the water to escape from the side hole, which isalways open. Whenever the end hole is open, the water will escape thereas if there were no side hole, because it will not change its directionto pass out of the side hole.

K indicates an annular projection upon the nozzle H for connecting itsecurely to the serpentine tube, as represented in the drawings. Theresult of this construction is that our improved serpentine sprinklercan be readily at. tached securely to place for operation, and it is notlikely to wear out or get out of order.

The operation is as follows: lThe plug C, when in place, checks the iiowof water from the hose A, and as the openings through the plug andthrough the serpentine tubes are smaller in combined transverse areathan the opening in the hose the result is that the pressure of water isincreased and the water spurts out of the nozzles of the serpentinetubes in small streams with considerable force.

IOO

The effect is to make the serpentine tubes Wriggle and gyrate or danceabout in the air in a very comical manner and in a very effective mannerfor sprinkling purposes. The Water is tossed about in the air in aninlnite variety of directions and separates into drops and falls allover the ground exactly like rain. A circle of about t-Wenty-iive toforty feet in diameter, according to the force of water-pressure, can bethoroughly sprinkled.

The serpentine sprinkler thus Works automatically, but Without drivingany machinery in the ordinary Way, and hence is economical and efcientwithout being` liable to Wear out or get out of order, because itcontains no re- -volving wheel or othervlike mechanism, and

it is a great practical advantage to provide,as illustrated, for the useof several wrigglers or sprinklers in a bunch.

Having described our improved serpentine sprinkler, what we claim to benew, and desire to secure by Letters Patent of the United States, is-

1. In a serpentine sprinkler, the combina tion of a tapering perforatedplug, C, adapted to be forced into the end ofa hose or the like, withtubes F, secured in holes in the plug, exible serpentine tubes G,secured to the tubes F, and nozzles H upon the free ends of the flexibletubes, substantially as set forth.

2. In a serpentine sprinkler, the combination of the internallyscrew-threaded cap E, adapted to fit over the coupling B, the taperingperforated plug G, forced into thecoupling B by the cap E, and theflexible serpentine tubes G, secured in the plug C and provided withnozzles H, substantially as set forth.

3. In a serpentine sprinkler, the combination of a tapering perforatedplug, C, adapted to beforced into the end ofa hose or the like, and thefeXible serpentine tubes G, connected therewith and provided with thenozzles I-I, substantially as set forth- In testimony whereof We havehereunto subscribed our names.
